Wireless networked control systems (WNCSs), consisting
of spatially distributed plants, sensors, machines, actuators
and controllers, play an essential role in the era of Industry
4.0 [1]}. In particular, remote state estimators for monitoring
dynamic plant status in a real-time manner are critical in
WNCSs to enable high-quality closed-loop control. In Industry
4.0, massive wireless sensors are deployed for remote state
estimation of spatially distributed plants.
This raises fundamental questions:
